Title: Buffer store in moving length of material - maintains folded amount by varying measured feed speeds, resets control by interposed detector
Inventor: UHL GERHARD DIPL ING
IPC: B65H20/24
Filed: 1979-11-16
Abstract: The arrangement maintains a constant length of continuously moving material (11), such as corrugated cardboard, in a buffer store (10). The material is laid in regular folds (11a) in the store whilst its length is continuously measured at the entry (13) and exit (14) of the store. The amount in the store is controlled by varying (at 15) the feed-in and feed-out speeds in response to the difference between these length measurements. To calibrate the measurement of the amount stored, the passage of the leading fold is detected at an intermediate position (18) in the store and the signal used to re-set the controller (15) so that the correct amount is again stored, e.g. after a splicing operation.

Title: Tape cassette drive control - has tape slack taken up before and after play-record modes
Inventor: MANGOLD HANS DIPL-ING
IPC: G11B23/087
Filed: 1980-07-05
Abstract: In the tape cassette, slack is taken up as the tape spools move forward to engage with the capstan and when they are retracted into the resting position. This provides uniform drive and prevents stretching of the tape. The central, projecting part of the spools slide forward in a slot (22) into the play/record position (23). They are pulled together by levers (28,29), consequently rolling on the outside edge which takes up any slack. Similarly, when retracking the spools roll along the inside edge and are finally locked in the serrated end position (24). Dust covers slide over the slots when the cassette is retrieved.

Title: Field detecting system for three=phase machine - produces voltages proportional to magnetic flux components using model circuit to simulate processes in machine
Inventor: BLASCHKE FELIX DR
IPC: H02P21/10
Filed: 1980-07-10
Abstract: The system has a current model circuit (1) receiving voltages proportional to the stator current (i) and magnetisation current and a rotor-position signal. The model circuit simulates those events in the machine that convert the currents into flux components and thereby produces signals describing the flux components. The circuit output signals are passed to a zero-point controller that eliminates the dc component in the difference between the flux component determined at the ac voltage integrator and the output of the model for this component. The advantage lies in the system's functioning at high and low speeds and in having low phase and amplitude errors that are independent of the machine frequency.
